![]() ![]() ![]() The AWS JDBC Driver for PostgreSQL is an advanced wrapper, and is drop-in compatible for the PostgreSQL JDBC Driver. How do I use the AWS JDBC Driver for PostgreSQL? Support for additional features of clusteredĭatabases, including features of Amazon RDS for PostgreSQL and on-premises PostgreSQL deployments, is Changes to the connection string is all that is needed. The driver is based on and is drop-in compatible with the PostgreSQL JDBCĭriver. It currently supports fast failover capabilities for Amazon Aurora with The AWS JDBC Driver for PostgreSQL is compatible with all PostgreSQL deployments, whether they be With this knowledge, the AWS JDBC Driver for PostgreSQL can moreĬlosely monitor the database cluster status so that a connection to the new primary DB instance can be This topology is provided via a direct query to the PostgreSQL database, providing a shortcut toīypass the delays caused by DNS resolution. It achieves thisīy maintaining a cache of the PostgreSQL cluster topology and each instance's role (replica or primary DB PostgreSQL is designed to coordinate with this behavior in order to provide minimal downtime. This process can take up to several minutes. Maximum availability to a primary read-write DB instance.īefore a replica instance can be promoted to the primary DB instance, the DNS record must be updated in order During failover,Īurora elects a database replica to become the new primary DB instance, so the cluster can provide In Amazon Aurora, failover is a mechanism by which theĭatabase automatically repairs the cluster status when a primary DB instance becomes unavailable. Supporting Fast Failover for Amazon Aurora Is optimally configured to allow an application to connect to and take advantage of the features of clustered A driver converts SQL queries in an application into a protocol language toĬommunicate with the database and returns query results to the application. HOW IT WORKSĭevelopers use software libraries, known as database connectivity drivers (or simply drivers), to connectĪpplications to databases. The AWS JDBC Driver for PostgreSQL supports fast failover for Amazon Aurora with PostgreSQLĮnhanced Failover Monitoring. This wrapper is complementary to and extends the functionality of an existing JDBC driver to help an application take advantage of the features of clustered databases such as Amazon Aurora. The Amazon Web Services JDBC Driver has been redesigned as an advanced JDBC wrapper. Amazon Web Services (AWS) JDBC Driver for PostgreSQL DOWNLOAD HOW IT WORKS BENEFITS FAQs ![]()
